Application alga April 2, 1925. serial No. 20,042.

My invent-ion relatesyto storage bins used for holding large quantitiesof heavy mate-l rial such as coal, "iron orelor the like, and such as,for example, are shown and described'in U. S. Patents Numbers 1,388,482and 1,338,488 issued to:` me -April 27th, 1920.

In a bin such as is yshown in either of'said patents, the bottomkportion thereof is apro.-

vided with a plurality of reinforcing or stifi0 vide the storage spacein such portion into a plurality of laterally arranged compartments.These partitions l have found serve as obstructions which frequentlycause the contents of the bin to'form fixed arches in and over. the saidcompartments, and impede or'stop: the required downward flow of thematerial, when it is desired to discharge same by gravity from thebottom of the bin.

The object of mypresent invent-ion is to' provide abin structure inwhich said arching and consequent obstruction to fiow of material bygravity,'is eliminated, and may bve-applied to either the flexible-sidedtype of bin shown in said patents, Qorfthe rigidsided type of bins whichis sometimes employed.

- his object I attainlby providing reinforcing or stiii'ening means forthebottom. portion of the bin of, such a character as will not includesaid previously described partitions and hence their attendantundesirableeitect. ,I This I accomplishfby securing exteriorly locatedstiilening means to thebottom portionfof the bin, which are so placed asto counteract the'tendency of the 'front and rear walls of suchportion,'to bulge outwardly.

- The annex'edldrawings and the 'following description set orth'indetail certain meansrv embodying my invention, the disclosed means,however, constituting but' one of the ifening diaphragms or partitionswhich "diand upon a` some- Fig. 2, and viewed in the direction indicatedbythe arrows.

Fig. 8 represents a section taken upon the plane indicated by line-VIII-VIIL Fig. 7. Fig.` 9 represents an end elevation of such modiiiedform, of bin bottom.

My present'invention, inthe form illustrated bly Figs. 1 to G inclusive,is shown to be applied to the suspended 'flexible-sided type of binshown in my above-mentioned patents, and in which the front and rearwalls converge downwardly as'shown, and \1vhi1ch is provided with'theverticalend walls The front wall consists of a main or upper portion 2anda bottom portion 3. The lat-k ter terminates a distance above thelower end of the bin to form a longitudinal rectanguiar dischargeopening` running the entire length between the twoendv walls 1-l, asshown in Figs. l, 2 and 4. This opening is vcontrolled by a multiplicityof gates 4 laterally juxtaposed as will vbe yhereinafter urvtherdescribed. f t

Theback wall consists of a main or upper portion 5 and a bottom portion6.-

. VThat portion of the end walls 1-1 which formsfthe end walls of thebottom portion of th'ebin, extends beyond the front and rearl walls ofsuch portion as shown in Fig. 8. For the purposes of convenience andassemblythese end wall portionsare made of separate plates .7-7 alinedwith the lower ends of the main end plates 8 8 by means of riveted flatbars 9-9 as shown in Figs. 2 and3.

Extending between the end plates 7-7,

' upon thel outside of the front and back walls and secured respectivelythereto by means ofangles 10-10, lare two horizontal supi ifo portingbeams 10-10, of -beam section preferably, the webs of which extend atright angles to said walls, as shown in Figs. 3 and ll. l

The upper part of both the rear and front extensions of the end plates7'-7 arev made of a width substantially equal to the depth .0f the beams10'-10.

Also for convenience of assembly and repair, the bottom wall portions 3and 6 are each made of a separate plate, the lower ends of plates 2 and5 being secured to the upper part of the inner flanges 11 11 of thebeams 10-10, and the upper ends of the plates 3 and 6 being secured tothe lower part vof such flanges by means such as the rivets shown, Figs.2 and 3. 'y l Intermediately of the gates 4l (betwee each adjacent pairas illustra-ted) are a plurality 4of rtensionV members 12,'made of plateand in contact with the .front plate 3. Each of these members is of ashape and size similar to that of the extended portion of the end plates7-7,'on the front of the bin, and has its upper end secured to the lowerside of the front beam 10 by means of suitable angles 12-12, Fig. l.

The front plate 3 may also be secured to the members 12 by means ofangles 3, asv

shown in Figs. 2 and 4.

Upon the lower end portion of the extenn sion of end plates 7-4-7 andthe member 12, are secured longitudinally alined brackets 13, whichsupport a rod 1li upon which the gates 4l; are pivotally mounted, asshown in Figs. '2 and 3. Each gate may be separately actuated throughthe medium of a suitable handle Ll attached thereto.

Each member 12 has its lower rear end portion extending backwardlythrough a slot 15, Figs. 5 and 6, cut in the bottom of the back plate 6,and each such rearwardly projecting portion of said members, is securedto the bottom of a rear tension member 16, of channel section, by meansvof an angle 17, Fig. 6.

'These members 16 lie against the .rear` plate 6 and each has its uppervend secured to the lower side ofthe rear supporting beam 10 by meansofl angles 18, Figs. 4 and 5.

The lower extremity of the bottom portion of the bin is reinforced by ahorizontal angle bar 19 secured to the lower end of the rear plate 6 andto the channel member 16, bysmeans of angles 20, Figs. i and 5, thelower ends of members 12 ybeing out out for that purpose as shown.

It will be seen from the above described arrangement that each connectedset of tension members 'l2 and 16 forms a. saddle or sling which issupported at its upper end by the two beams,l0-10, the latter beingsupported by the upper part of the bin,

i such slings reinforcing thetwoplates 2 and 6 and counteracting their.tendency to bulge outwardly when the force due to theweight of the loadin the bin, is applied thereto. These reinforcing members being, asdescribed, located entirely upon the outside, the innerastora'ge-spaceofl the bottom portion of the bin is freeandunobstructed so that the arching previously referred to is eliminatedor at leastminimized.

inventionv as applied to a bin of the suspended type and -in which thedischarge openings are placed centrally at the bottom. ln this form thefront and back walls7 3 and G respectively, of the bott-om portion areeach yreinforced by longitudinal horifl zontal -beamsflQl, the uppermostoflwhich,

21, are secured to the lowerend-portion of the main front andback walls,2 and 5`re`- spectively, the en'dwalls-? being alined with the end walls1 1, as in the first described structure.

As shown, theseAI-beamsV are allsecured to the exterior of walls 3 and 6and their ends secured to the end-,walls 7-7, by means of suitableangles 22, said end walls being extended front and rear for thatpurpose, as shown in Fig. 9. l

This modified form, therefore, has its front and rear walls exterior-lyreinforced to prevent them from bulging outwardly, but the reinforcingmeans are not suspended or of sling form as inthe first-described formof my invention. it will also be apparent to those skilled in the art,that the described sling method of reinforcement may be applied to a binhaving its discharge openings centrally placed. Fiitlier type ofreinforcement may be used in connection with .a bin of the form shown inFigs.,71 to 9, but the sling-type of reinforcement is particularly,suitable to the type ofibin, shown in Figs. -11 to 6, and "in which theopenings yare in the, side rather than centrally at the. bottom, allaswill be understood by those familiar Vwith the art. What I claim is:j 1. A storage bin formed with an upper portion and a rigid bottomportion =having front and rear walls, and external rein-force ing meansfor saidfrontandrear walls suspended from said upper portion. n

2. A storage Vbin comprising an l'upper portion having flexible,suspended front and rear walls, anda rigid bottom portion having frontand rear walls, and means suspended from ysaid bin land adapted to veX-Figs'7, 8 fand`9 illustrate a feature of my iso Y the front and rearwalls of said bottom porrear walls, said sling acting as a stiffeningmember for the front and'rear walls of the bottom portion andintermediately of the end vwalls thereof.

5.. A storage bin having .anV upper portion and a bottom portionincluding two end walls, front and rear walls, and amultiplicity ofslings supported by the upper portion oi the bin, located upon theoutside of said bottom portion and supporting the 'said front and rearwalls. y y
